Re: +1 for X220 mention
"Your humble hack's old X220 is one of the last units with the old-style keyboard, which is why it's in service six years later despite being so slow to boot you can make a cup of tea and be back before it's ready to use."
X220 + SSD + no-name battery = boot in 45 sec (cos Slackware) seriously snappy and fully functional.
Time for a reinstall?
Comment on OA: 4:3 ratio and same form factor as X60 but with bright non-reflective screen and 12 hour battery life and I'll buy two.
